Evaluation of the impact on diet of the school fruit and vegetable scheme (SFVS).
Non-randomised controlled trial.
Infant and primary schools in the north of England.
3,703 children aged four to six years (reception, year 1, and year 2).
One portion of fruit or vegetable provided per child on each school day between February and December 2004.
Fruit and vegetables consumed and intake of nutrients.
The SFVS was associated with an increase in fruit intake across reception and year 1 pupils of 0.4 portions (95% confidence interval, 0.2 to 0.5) and 0.6 portions (0.4 to 0.9), respectively, at three months, which fell to 0.2 (0.1 to 0.4) and 0.3 (0.1 to 0.6) at seven months. In year 2 it was associated with an increase of 0.5 portions (0.2 to 0.7) of fruit at three months, which fell to baseline values at seven months when these children were no longer eligible for the scheme. Overall, at seven months there were no changes in vegetable consumption, no associations between the SFVS and energy, fat, or salt intake, and small changes in carotene and vitamin C intake.
The SFVS promoted an increase in fruit intake after three months. At seven months the effect remained significant but reduced, and it returned to baseline in year 2 when pupils were no longer part of the scheme. There was a small impact on the intake of some nutrients across the children surveyed.
评估学校水果和蔬菜计划(SFVS)对饮食的影响。
非随机对照试验。
英格兰北部的幼儿园和小学。
3703名4至6岁的儿童(学前班、一年级和二年级)。
在2004年2月至12月期间,每个上学日为每个孩子提供一份水果或蔬菜。
水果和蔬菜的摄入量以及营养素的摄入量。
SFVS与学前班和一年级学生的水果摄入量增加有关,三个月时分别增加了0.4份(95%置信区间,0.2至0.5)和0.6份(0.4至0.9),七个月时降至0.2份(0.1至0.4)和0.3份(0.1至0.6)。在二年级,三个月时水果摄入量增加了0.5份(0.2至0.7),七个月时降至基线值,此时这些孩子不再符合该计划的资格。总体而言,七个月时蔬菜消费量没有变化,SFVS与能量、脂肪或盐的摄入量之间没有关联,胡萝卜素和维生素C的摄入量有微小变化。
SFVS在三个月后促进了水果摄入量的增加。七个月时效果仍然显著但有所降低,二年级时当学生不再参与该计划时又恢复到基线水平。对所调查儿童的一些营养素摄入量有微小影响。
